Entropy generation analysis on zero mass flux effects of nonlinear mixed convective Williamson nanofluid flow with christov-Cattaneo heat flux

The passage of non-Newtonian fluids across the stretching plate exerts a significant impact and finds applications in various industrial sectors, such as fluidics networks, fluid agitation, thermal reactors, liquid chromatography, semiconductors, tissue regeneration, and gene delivery to organs. In this study, we investigated the hydrodynamic Williamson nanofluid flow over a stretchy surface with zero mass flux, Christov–Cattaneo (C–C) theory, non-linear mixed convection, and passive controls of nanomaterials. Thermophoresis and Brownian motion impressions are also taken in the present flow. The second law of thermodynamics is also used to determine the entropy generation. By using the proper similarity alterations, the PDEs (governing equations) are converted into non-linear ODEs. To crack the non-linear ODEs, the homotopy analysis method is used. There is a detailed discussion of the effects of magnetic, Weissenberg, radiation, Brownian motion, the Bejan parameter, and the entropy creation of various factors. Additionally, the heat, mass transfer rate, and skin friction are assessed. Also, compare skin friction and the Nusselt number with previous studies. The Weissenberg number and Brinkman parameter shows the opposite tendency in entropy generation and Bejan number profiles.
